Background In early RA, the benefit of treatment with b-/tsDMARDs on work participation (WP), a top-three social role in RA, has seldom been studied. Objectives To review the effect of treatment with b-/tsDMARDs on employment status (ES), presenteeism and sick leave (SL), in patients with early RA. Methods A systematic literature review (SLR) was conducted in key electronic databases up to October 2021, to include RCTs assessing the effect of treatment with b-/tsDMARDs vs any comparator on ES, presenteeism and SL in patients with RA (≤ 3y). Two reviewers independently identified eligible studies and extracted data. Random-effects meta-analysis was only performed if ≥3 studies were conducted in comparable populations, assessing WP outcome similarly. Statistical heterogeneity was assessed with I 2 . Results From 7129 records (65 full-text articles screened), 11 RCTs were included in the SLR (7 in csDMARD naïve patients; 2 in inadequate responder to csDMARDs; 1 bDMARD tapering after initial combination with MTX, and 1 strategy study). Large heterogeneity was found across WP outcomes, measurement instruments, interventions and comparators (Table 1), which together with insufficient data reporting hampered meta-analysis of most outcomes. For ES, to allow meta-analysis, all outcomes were converted to employment loss, for which individual study Odds ratios (OR) were computed. The pooled OR of 4 studies with 779 patients treated with adalimumab, infliximab or baricitinib (Figure 1) showed a lower likelihood of employment loss at weeks 56 to 104 in those treated with MTX+b/tsDMARDs compared to MTX+PBO (OR: 0.65; 95% CI:0.43-0.99). For presenteeism and SL, 33/40 (83%) between-group comparisons showed improvement in favour of b-/tsDMARDs, but an effect size was reported or possible to compute for only 12 comparisons, of which 8 (67%) were statistically significant.

Conclusion A protective effect against employment loss was observed in patients with early RA treated with MTX+b-/tsDMARDs compared to MTX monotherapy. The methodological heterogeneity and insufficient reporting hampers clear conclusions regarding the beneficial effects of b-/tsDMARDs on presenteeism and SL. Efforts to uniformize future studies with WP as outcome by following recently developed points to consider are crucial 1 . References [1]Boonen A, et al. Ann Rheum Dis. 2021; 80:1116-1123.
